This invention relates to an automatic back verse brace or shelf 11. Each standard scratcher for animals and more particularly has mounted thereon a slide 12, which is to a device of this character which will not connected to the standard by bolts 13 and only provide a scratching mechanism but passing through the slide and through verti- 15 which will likewise oil the animal during the cal slots 14 formed in the standard. Each 50 scratching operation. bolt is surrounded within the slot by a roller A further object of the invention is to prosleeve 15 reducing the frictional engagement vide a device of this character which will ofthe bolt with the slot and permitting ready automatically adjust itself to the height of vertical movement of the slides upon the 10 the animal employing the same and which is standard. Connecting the slides 12 is a bar 55 so constructed that it may readily be com- 16, which is hinged to each slide, as indicated bined with one or more devices of the same at 17, so that either slide 12 may be shifted character, l g g upwardly independently of the other slide.
